nwz..um in 2005 it came it was 2 marks, even then it was an application question u could pretty much make it up on the spot

T1 and T2 are relaxation times . By distinguishing between the relaxation times of different tissues, computers can determine the type of tissue and thus produce an image. T1 images are produced by rapidly turning the radio pulse on and off. As a result T1 tissue continuosly energise and relax...

also its low in density

sweeet...thanks dude (Y)

hey guys i just wanted to ask a quick question...a property of the hypothetical aether was that it has to be very elastic to allow the propagation of light..why does it have to be elastic? for wat wave property does this feature accomdate? thanks =)

I believe both an increase in intensity and frequency would yield a larger photocurrent: Increase in intensity; would mean more electrons are being librerated as there are more photons bombarding the metal surface. Since current is a flow of electrons, the more electrons that a liberated the...

y=e^f(x) 1. when f(x) = 0 , y=1 2. y CANNOT be negative, a good way to check if ur graph is correct or not. y=ln{f(x)} 1.When f(x) = 0, a vertical asymptote exist at the corresponding x value 2. When f(x)=1, y=0 3.f(x) CANNOT be < 0, to draw y, in other words whenever f(x) is <0 ignore dat...

ahhhh thanks guys really appreciated

hey guys, just wanted to ask a quick question. if you had to find the sum of the roots of the equation x^3-3x+5=0, how do u got about doing it since in this particular question the powers of x do not fall from cubic to quadratic to linear, rather it falls from cubic to linear. in other words...

the best books imo are: 1.Cambridge 2.coroneous 3.fitzpatrick 4.couchman and jones 5.Maths in focus

here are mine...

ah sorry must say an agar plate in a closed petri dish

welll if u said a petri dish containing the nutrient agar it would be allright it depends entirely on how u set out ur procedure to investigate microbes in drinking water

ive attached the solution to the derivative question 2e^2x - e^x = 0 e^x(2e^X-1)=0 e^x=o has no solution 2e^x=1 e^x=0.5 x=ln0.5

if u mean for the question :find the derivative of y=ln(e^x sin^2 x) thats incorrect...u should start off with y'=u'v+v'u ---------- f(x)

the intergral of sinx/cosx .dx = -lncosx + c find the derivative of y=ln(e^x sin^2 x)

hey guys im kinda worried, i wrote my student number and centre number on all the pages in the option answer book however im not sure if i wrote it on 2 pages that i wrote my answers on in the same booklet it would still be marked right ??

basically the important information u need to know about crossing over and random segregation is: crossing over: is basically the exchange of genetic material between 2 chromatids as a result they increase the combination of genes on the same chromosoem, thus increase variation in...

guys just a quick question does both active and passive transport occur in the phloem or just active?

early 1700s- Linneaus classified humans with apes 1735-erasmus darwin said that all life came from a single source 1809- lamarack published his theory of evolution by the inheritance of aquired characteristics, which is based purely on the use and disuse of body parts. 1859-darwin publish the...
